I purchased 2000 unqualified shares of my former UK-based employer, and was required to sell them back at a loss when I quit my job. I'm trying to claim this as capital loss, and see the form 3520 is clearly related to my situation... however, it isn't supported by turbotax, and I'm not sure if I should also fill out form 1099-B so that the loss is registered in my income section?
PS I'm quite bitter about the situation so I'm hoping the least I can do is get the $400 or so back in tax refunds!
Yes, you would need to report this in the stocks and bonds section of the return. You wouldn't report it like a 1099B since you don't have it but report in the following manner.
